Over the years, readers have sent some wonderful questions for the Mailbag in the Sunday outdoors page in the Sun-Times, but Dave McDonald sent a first of its kind whaisit.
``While out metal detecting recently I found a metal tag. The tag says 1938 Illinois Dept. Conservation and a number--V17646. Is this an old deer tag or something else?''
That is the kind of question I love.
I reached out to Mike Conlin, who retired a couple years ago as chief of Illinois' office of resource conservation and had three decades prior to that as Illinois fisheries chief.
He said, ``A quick look makes me think that it is a tag for a basket trap, seine, hoop net or gill net.''
Conlin said that in 1907 the first commercial license was required in Illinois to use a seine to harvest fish.
That fits with where McDonald, in a follow up e-mail, told me that he found it in ``a park in South Holland'' next to the Calumet.
